Answer:
[tex]s = \sqrt{2a} [/tex]
Step-by-step explanation:
A = 0.5S^2
2A = S^2
Therefore,
[tex]s = \sqrt{2a} [/tex]
To express the length in terms of the area, is an illustration of change of subject of formula.
The equation that express S in terms of the area is: [tex]S =\sqrt{2A}[/tex]
Given that:
[tex]A = \frac 12S^2[/tex]
First, multiply both sides by 2
[tex]2 \times A = \frac 12S^2 \times 2[/tex]
[tex]2 \times A = S^2[/tex]
[tex]2A = S^2[/tex]
Take positive square roots of both sides
[tex]\sqrt{2A} = \sqrt{S^2[/tex]
[tex]\sqrt{2A} = S[/tex]
Rewrite the equation as:
[tex]S =\sqrt{2A}[/tex]
Hence, the equation that express S in terms of the area is: [tex]S =\sqrt{2A}[/tex]

3.5 + 1.2(6.3-7x) =9.38
Answer:
x = 0.2
Step-by-step explanation:
Order of Operations: BPEMDAS
Step 1: Write out equation
3.5 + 1.2(6.3 - 7x) = 9.38
Step 2: Parenthesis (distribute)
3.5 + 7.56 - 8.4x = 9.38
Step 3: Combine like terms (constants)
11.06 - 8.4x = 9.38
Step 4: Subtract 11.06 on both sides
-8.4x = -1.68
Step 5: Divide both sides by -8.4
x = 0.2

You have $55 in your bank account, and you would like to buy a new phone for $395. You can save $5 for each hour you work. How many hours must you work to buy it?
Answer:
(At least) 68 hours
Step-by-step explanation:
So we already have $55 in our bank account.
And we earn $5 per hour.
In other words, the total amount of money in our account after working x hours is represented by the equation:
[tex]y=5x+55[/tex]
We want to buy a new phone that costs $395. To find out how many hours we need to work, substitute 395 for y. Thus:
[tex]395=5x+55[/tex]
Subtract 55 from both sides:
[tex]340=5x[/tex]
Divide both sides by 5:
[tex]x=68[/tex]
Therefore, we must work for (at least) another 68 hours in order to earn enough money to purchase the phone.
evaluate the expression for the given value of the variable 9 | 9 -8x | = 2x + 3
Steps to solve:
9|9 - 8x| = 2x + 3
~Divide 9 to both sides
|9 - 8x| = 2/9x + 1/3
~Solve absolute value (part one)
|9 - 8x| = 2/9x + 1/3
-74/9x + 9 = 1/3 (Subtracted 2/9x to both sides)
-74/9x = -26/3 (Subtracted 9 to both sides)
x = 39/37 (Multiplied 37/39 to both sides)
~Solve absolute value (part two)
|9 - 8x| = -(2/9x + 1/3)
|9 - 8x| = -2/9x - 1/3 (Distributed negative sign to left side)
-70/9x + 9 = 11/3 (Added 2/9x to both sides)
-70/9x = -28/3 (Subtracted 9 to both sides)
x = 6/5 (Multiplied 9/-70 to both sides)
Therefore, the solutions are x = 39/37 and x = 6/5

Solve 10-13 find each measurement
Answer:
10)17.5
11)18
12)70
13)110
Problem 10
Answer: RS = 17.5This is because the opposite sides of any parallelogram are congruent (PQ = RS and QR = PS)
======================================
Problem 11
Answer: QT = 18Diagonal QS is cut in half (bisected) by the other diagonal PR. The smaller pieces QT and ST are the same length.
======================================
Problem 12
Answer: angle PQR = 70 degreesThe angle QRS is given to be 110 degrees. Angle PQR adds to this to get 180, so we effectively solve x+110 = 180 to get x = 70. Any pair of adjacent angles of any parallelogram are supplementary.
======================================
Problem 13
Answer: 110 degreesOpposite angles of a parallelogram are congruent. Angle SPQ is opposite of angle QRS = 110.
Find the sum of 4x2 – 7 and 6x2 – 5.
Answer:
the answer is 1 and 7
Step-by-step explanation:
4 times 2 is 8 -7 =1
6 times 2 =12 -5 =7
Answer:
First problem equals 1 and second problem equals 7.
First multiply 4x2 to get 8, then subtract it by 7. That would leave you with 1.
Now, 6x2 would be 12 minus 5 which would equal 7.
Carina begins to solve the equation Negative 4 minus two-thirds x equals negative 6 by adding 4 to both sides. Which statements regarding the rest of the solving process could be true? Select three options. After adding 4 to both sides, the equation is Negative two-thirds x equals negative 2. After adding 4 to both sides, the equation is Negative two-thirds x equals negative 10. The equation can be solved for using exactly one more step by multiplying both sides by Negative three-halves. The equation can be solved for x using exactly one more step by dividing both sides by Negative two-thirds. The equation can be solved for x using exactly one more step by multiplying both sides by Negative two-thirds.
Answer:
options 3 and 4 are correct
Step-by-step explanation:
And form the remainder of the problem, you isolate x by just multiplying by the negative reciprocal, which is -3/2, or just dividing by the number in front off x, which is -2/3, which makes statements three and four true. so this makes this three and four options

You found hardwood flooring priced by the square foot. To find the price per square yard, you should do which of the following.
a.) Divide the price per square foot by 9
b.) Multiply the price per square foot by 3
c.) Multiply the price per square foot by 9
d.) Divide the price per square foot by 3
Answer:
D. Divide the price per square foot by 3
Step-by-step explanation:
1 foot = 0.333333 yard
price per square yard of the hardwood = price per square foot / 3
For instance, If the price per square foot is $900, then the price per square yard is
price per square yard of the hardwood = price per square foot / 3
= 900 / 3
= 300
price per square yard of the hardwood = $300

A basketball court is shaped like a rectangle 20 meters long and 10 meter
wide? What is the area of the court?
Answer:
200 squared meters.
Step-by-step explanation:
Since we know the court is a rectangle, we can use the formula for the area of a rectangle:
[tex]A=lw[/tex]
Where l is the length and w is the width.
We are given that the length is 20 meters and the width is 10 meters. Substitute:
[tex]A=20(10)[/tex]
Multiply:
[tex]A=200\text{ meters}^2[/tex]
So, the area of the court is 200 squared meters.
